Automatic calculation of measurement confidence in flexible modular plants and machines

Abstract

The invention provides a method for providing an output value with associated uncertainty for a flexible modular plant or machine comprising an arrangement of modular entities (21-2n). The uncertainty information associated with the operation of the modular entities (21-2n) is assigned to a plurality of the modular entities (21-2n). Input values are provided based on the operation of the modular entities (21-2n). A calculation unit (12) calculates an output value based on the input value. A calculation unit (12) calculates an input value uncertainty for each input value based on the uncertainty information of the modular entities (21-2n). A calculation unit (12) calculates at least one output value uncertainty associated with the output value based on the propagation of the uncertainty and using the input value uncertainty. The output value and the at least one output value uncertainty are output.

Description

technical field [0001] The invention relates to a method and a device for providing output values ​​with associated uncertainties for a flexible modular plant or machine. Background technique [0002] A manufacturing plant based on modular entities is beneficial in terms of increased flexibility in plant layout, reduced safety concerns during construction of the modular plant, and easier modification and replacement of the modular entities. [0003] The modular entities or devices of such a flexible modular factory may include components such as wires, walls, pipes, machines, actuators and sensors. Modular entities are installed according to a specific arrangement that describes the manner in which the modular entities are connected to each other. [0004] Sensors measure physical and chemical properties and provide measurement data subject to measurement uncertainty. The degree and type of uncertainty may be specified in the documentation for the respective sensor and may...
